Is anyone else having an issue with receiving voice mails with power saver mode turned on? I call both Verizon & Samsung and there is no fix other than to not use power saver mode. My problem is without power saver mode turned on and with all apps shut down my battery will drain in less than 5 hours. Another issue is NO audible warning than the battery is low. With my S5 I used to receive warnings both audible and visual when my battery got to 20%.
